PowerFlex 700S Phase II AC Drive User Manual -
Publication 20D-UM006G-EN-P – July 2008
Auxiliary Power Supply (High Power Only)
You may use an auxiliary power supply to keep the 700S Control Assembly
energized when input power is de-energized. This allows the Main Control
Board, DriveLogix controller and any feedback option cards to continue
operation. Refer to
Power Terminal Blocks on page 1-9
for connection
information. You must set bit 17 “Aux Pwr Sply” of Par 153 [Control
Options] to enable this feature. Refer to the PowerFlex 700S Auxiliary
Control Power Supply Installation Instructions (PN: 20-24V-AUX1),
publication 20D-IN021… for more information.
Important: For frame 9 - 13 drives manufactured prior to June 2006, the
Voltage Feedback board provides the bulk 24 volts for the High
Power Fiber Optic Interface board. If the auxiliary power
supply (24 volts) is greater than the Voltage Feedback board (24
volts) then the switch mode power supply on the Voltage
Feedback board will shut down. If the auxiliary power supply
has an adjustable voltage, then the voltage should be lowered
(23.75). This will allow the Voltage Feedback board power
supply to supply the 24 volts. If the auxiliary power supply
cannot be adjusted, then a 500 ohm resistor needs to be added
to the Voltage Feedback board. In this case, please contact
Drives Technical Support for details.
Hardware Enable Circuitry
By default, Digital Input 6 is configured for hardware enable input. This is
for applications requiring the drive to be disabled without software
interpretation. With the “HW Enable Jumper (Shunt)” on the pins closest to
the PCB (2-4), Digital Input 6 is configured as a “dedicated” hardware
enable. If this configuration is not required, the “HW Enable Jumper
(Shunt)” may be moved to the out board pins (1-3), making Digital Input 6
user programmable via Par 830 [Dig In6 Sel].
